Supported Chipset & RAM Compatibility

The U-SMU1 is particularly valued because it covers a wide range of generations, from legacy mid-range chips to modern 5G processors.

Processor (CPU) Support:

• Exynos 800 Series: 850, 880

• Exynos 900/1000 Series: 980, 990, 1080, 1280

• Exynos 7 Series: 7870, 7884, 7885

• Legacy/Mid-range: 8895, 3475, 9610, 3830

RAM Support:

Specifically includes patterns for the LPDDR memory chips often layered on top of these CPUs:

• RAM 496

• RAM 556

Key Features for Technicians

• Precise Alignment: The stencil features laser-cut apertures that align perfectly with the IC pads, reducing the risk of bridges.

• Anti-Bulge Design: The cooling holes and material choice help the stencil remain flat even when subjected to the high temperatures of a quick-heat air station.

• Multi-Model Layout: Instead of carrying ten different stencils, this single plate covers the majority of Samsung A-series and S-series repairs from the last several years.

Pro Tip: To get the best results with this stencil, use 183°C leaded solder paste and ensure you wipe the stencil clean with anhydrous alcohol between every heat cycle to prevent carbon buildup in the apertures.
